Summary
P2P module should not backoff+retry for connections to peers where there is a chain mismatch, but should expunge the address from the address book and remove it from the list of peers.
Problem Definition
Presently (v0.33; not sure if this is addresses in 0.34), if we connect to a peer on an incorrect chain, the node repeatedly reconnects to this node, and then drops the conn
